Pearl Harbor Was Allowed to Happen

This theory states that President Roosevelt (FDR) provoked the attack, knew about it in advance and covered up his failure to warn the Hawaiian commanders. FDR needed the attack to sucker Hitler to declare war, since the public and Congress were overwhelmingly against entering the war in Europe. It was his backdoor to war.

Theorists believe that the US was warned by, at least, the governments of Britain, Netherlands, Australia, Peru, Korea and the Soviet Union that a surprise attack on Pearl Harbor was coming. All important Japanese codes were broken. FDR and Marshall and others knew the attack was coming, allowed it and covered up their knowledge.
